I would suggest you to use zcmd and sscanf. (sscanf isn't needed, but i prefer using it)

pawn Код:

command(boom, playerid, params[])
{
     new pID;
     if(sscanf(params, "u", pID)) return SendClientMessage(playerid, COLOR, "usage: /boom [ playerid / name ]");
     // GetPlayerPos(pID, x, y, z) and shiiit here.
     CreateExplosion(player2x, player2y, player2z, 7, 10.0);  //this kills player 2     
     return 1;
}
